History

Historical Context

In 2009, the U.S. Environmental Protection Agency (EPA) classified six greenhouse gases as harmful, following the Supreme Court's 2007 ruling in Massachusetts v. EPA that mandated regulation under the Clean Air Act. This decision marked a significant shift in environmental policy, leading to ongoing legal battles, including California's lawsuit against the Trump administration's rollback of these regulations, highlighting tensions between state and federal authority in climate action.
